FlexTop 2202 Temperature Transmitter
Description
FlexTop 2202 is a 4...20 mA loop-powered transmitter for Pt100 sen-sors.
Either 2-, 3- or 4-wire sensors can be used. For 2-wire sensors an automatic balancing of the sensor cable resistance is possible with shorted sensor cable. The cable resistance can be manually config-ured as well.
Using a PC, the Windows-based Flex-Program and a FlexProgrammer configuring unit, the following parameters can be configured via the output connectors (2-way communication): TAG no., number of wires, cable resistance, error detection level, measuring range/unit, damping, offset and status indication.
The Flex-Program has a datalogging facility enabling the user to moni-tor measuring results or calibrate the measuring setup.
FlexTop 2202 is embedded in silicone which makes it resistant to humid environments.
FlexTop 2202, fitting into the DIN B housing, has a 6 mm center hole for quick sensor replacement. The spring loaded mounting screws ensure a safe fastening even in vibrating environments.
